Application filed May 16, 1911.` Serial No. 627,596.

T all whom it muy concern Be it known that I, EDGAR L. FULLER, a citizen of the United States, residing in Everett, county of Middlesex, and State of Massachusetts, have invented an Improve ment in Hammocks, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like arts.

p This invention relates to a hammock of that class in whicha rigid mattress supporting frame is suspended from an overhead support.

YThe present invention has. for its object to provide hammocks of the class described with head and foot pieces which are capable of being moved from a substantially vertical position into various .angular positions, whereby the full length of the hammock is available, when the occupant desires to lie down full length, and wherebT either end piece may be inclined and used Vas a support for the back and head of the occupant,when the latter desires to assume a sitting position. Y i y These and other features of this .invention will be pointed out in the claims at the end of this specication. i

Figure 1 is a side elevation of one form of hammock embodying this invention. Fig. 2, an end elevation of the hammock shown in Fig. 1. Fig. 3, a detail in plan on an enlarged scale of a portion of the mattress supporting frame, and Figs. 4 and 5, details to be referred to.

In the present instance, I have shown one known construction of hammock which comprises a mattress supporting frame composed ofside rails, rods or bars a and end bars or rods Z), preferably metal pipes which are suitably connected together to form an open frame within which is located a bottom composed of links o connected together and yieldingly secured to the side and end bars or rods a, I) by springs CZ, and upon which the mattress e is supported.

The mattress supporting frame is suspended from an overhead support of any suitable construction and not herein shown, and in the present instance said frame is suspended by link chains 10 secured at their lower ends to the side bars or rods a near the opposite ends of the same.

The hammock as thus far described may be of any usual or well-known construction,

and the present invention has for its object to provide the saine at one end and preferably at both ends, with an end piece or frame, which is adjustable into different angular positions to form a support for the back of the person using the hammock.

In the present instance I have shown a back support at each end of the hammock, and as both are alike a detailed description of one will suffice to enable the invention to be understood.

The back supporting piece herein shown comprises a frame preferably of metal and provided with extensible side bars or arms, and in the present instance the upper member of each side arm is made as a hollow pipe or tube l5, open at its lower end and pivotally secured at its upper end to one of the side chains l0 by `a pin or rivet 1G. The upper member 15 of the side arms on opposite sides of the hammock are shown as connected by a cross piece 17 of piping, which is integral with the upper member 15.` Each side arm is provided lwith a lower member, preferably made as herein'shown and comprising a rod 18, which has its upper end inserted into the upper member 15, and has its lower end pivotally secured by a pin or rivet 20 to the free ends of a strap 21,which isbent substantially at its middle to form an eye 22 of greater diameter than the side rod a ofthe mattress supporting frame, so that the said eye can be moved longitudinally thereon. The eye 22 may be practically closed by a block 23 of metal, which is interposed between the arms 21 of the strap and is secured thereto by the rivet 241. The space between the upper members of the side arms may be closed by a piece 25 of canvas, duck or like material, and a pillow 26 may be detachably secured to the link chains and rest on the canvas piece 25.

In operation, the back supporting frames are normally in a substantially vertical upright position as shown at the right in Fig. l, and when in this position, the hammock may be utilized for its full length.

When the occupant of the hammock desires to recline in the hammock with the head elevated, the eyes 22 of the lower meinbers of the back supporting frame are slid along the side bars or rods a, until the said frame has been moved into the desired angular position as represented at the left in Fig. 1f. Ast-he eyes 22 are slid along the side rails or rods a, the rods 18 are partially ing the side bars or rails a suiiciently to cause them to engage upper and lower edges of the eyes 22, after the manner represented in Fig. 1. In either casethe back-supporting frame is securely held in its adjusted position. I

I have herein shown one construction of adjustable supporting frame for the hammock7 but it is not desired to limit the invention to the particular construct-ion shown.

The mattress e may be of any usual construction, such as now commonly employed in hammocks of the character described.

Claims. 1. The combination with a hammock promvided with a mattress-supporting frame having side rails, and iiexible means connected at their lower ends with the mattresssupporting frame to suspend the same, of a "'j movable baclcsupporting frame having its rails of said mattress supporting frame, sub#- upper end interposed between said flexible means and pivotally connected thereto at its opposite sides and having extensible yside arms in sliding engagement with Vthe side stantially as described. Y

2. The combination'with a hammock prolvided with a mattresssupporting `frame hav ing side rails, v'and means to suspend the same, of a movable back supporting frame pending means, rods extended into: saidi` tubular arms, and straps pivotally connected with said rods and provided with eyes' through which the side rails oif the .mattress supporting frame extend, substantially Vas described. v

8. The combination with a hammock vprovided with a mattress-supporting frame having side rails, and link chains connected at their lower ends :with the" Vsaid fra-me near the ends thereof, of a movable back-supportV ing frame interposed. between thesaid link chains and having tubular sidearms pivoted near their upper ends to said link chains and having extensible lower arms movable in said tubular arms and insliding engage! ment with the side rails of said mattress; i supporting frame,` substantially as described;

4. `The combination with-ahammock pro;`
